Brief summary
The purpose of this study is to study the positioning and stabilization of different cardiac walls performed during off-pump coronary artery bypass grafting (CABG) may have dissimilar impact on hemodynamics. The objective is to evaluate hemodynamics during distal coronary anastomoses in different cardiac walls.
Detailed description
* Twenty patients undergoing off-pump CABG monitored with pulmonary artery catheter and esophageal doppler will be enrolled. * Patients with a left ventricular ejection fraction \<50%, age \>80 yr, creatinine \>1.4 mg/dl, reoperation, valvular heart disease or chronic obstructive pulmonary disease were excluded * Data will be collected after volemic and hemodynamic adjustments, after heart positioning and establishment of a suction stabilizer and before its removal in anterior, lateral or posterior wall artery anastomosis. * Data was compared by means of two-way repeated measures ANOVA.
